Clin Infect Dis 59:1705-10
Diagnosis of Lyme disease in late-stage patients is often erroneous. Fallon and colleagues compared Lyme disease test results from four different testing labs, using blood samples from previously diagnosed Lyme patients and healthy controls. Overall, they found variation in results, but no statistically significant difference between labs. However, there was a higher positivity rate for the C6 test, than for whole bacterial sonicate used in the diagnostic test.
